Any interest for a library to control the ultra low power Sharp Memory LCD displays, like this one from Adafuit?
The library has been written from scratch to be sufficiently resource optimized that it fits into Z-Uno projects. It provides the following functionalities:

No problem. I need still a few days to clean up and document things and will contact you then to discuss the project transfer. The project is a radiation monitoring system and I use it to measure the radiation in the cellar due to the infiltration of radon gas (I leave in a radon rich region). Radiation, temperature and humidity data are displayed on the Sharp display as well as transferred via Z-Wave to a controller.

But we start discussing things outside of the main topic here. We should come back to the discussion about library needs ...

Looks interesting! Seeking forward for you to finish it. We would be happy to present photos of your device, schematics and sketchs to share with other users. With credits to you of course and only if you want it to share. Up to you.

Definitely! I'm waiting for the Z-Uno in Australia, so that I can monitor water tank levels by z-wave. It would be great to have a screen showing the levels at the tank also. This Sharp display looks like a good fit for me!

The Sharp Memory LCD display library is now available on Github (use this link).
And the Z-Uno radiation monitoring application is also available on Github (use this link).
In case of problems please use the Github issue tracking system to submit your problems. Feedback is welcome!
If the z-wave.me team would like to add the library to the Z-Uno software distribution and/or the application to the Z-Uno project page, please contact me (just respond to one of my mails from Jan 29 or Feb 6).

Another nice feature to support would be the Nextion touchscreens (https://nextion.itead.cc/). You can get one from 20 EUR (up to 100..) depending on the size but can be used to build typical touchscreen for the living room to manage full home automation control center.
This kind of TFTs has their own IDE to design and build WYSIWYG screens and applications. then you can connect with Arduino via serial port.

thanks
